Using this screen shot as an example I'm trying to figure out how to calculate each group of option groups AND calculate the total score with weighting applied.

So for example... Group #1 is actually made up of 4 option groups and the average of the 4 option groups is to equal 60% of the overall total score.

Group #2 is actually made up of 2 option groups and the average of the 4 option groups is to equal 30% of the overall total score.

Group #3 is actually made up of 5 option groups and the average of the 4 option groups is to equal 10% of the overall total score.

I know how to average each of the 3 group scores but I can't figure out how to apply the weighting to the overall score.

Make sense?
